Mailgun Docs MCP

Mailgun Docs MCP

By Sinch

Mailinite Outbound Readiness

Mailinite Outbound Readiness

By Kashif Khan

Mailinite Outbound Readiness tells you whether your cold email setup is ready to send, and what to fix first. What it does: - Audits a sending domain with live DNS lookups: MX records, SPF (including the 10-lookup limit and redirect handling), DKIM at common provider selectors, DMARC policy and reporting, domain blocklists (Spamhaus DBL, SURBL, URIBL), domain age from the registry's RDAP record, and whether the domain resolves. Each check returns pass, warn or fail with a specific fix, plus a 0-100 score. - Plans sending infrastructure for a monthly volume: daily sends, active and spare inboxes, number of sending domains, new prospects needed per month, warm-up time and a three-week ramp. All assumptions (emails per inbox per day, inboxes per domain, spare capacity, warm-up days) can be changed, and you can add your own prices for a cost estimate. - Scores overall outbound readiness from 0 to 100 by combining the domain audit and capacity plan with your answers about separate sending domains, warm-up, list verification, bounce rate, opt-out, open tracking and ICP, then lists the top fixes in priority order. Who it's for: founders, sales teams and agencies about to start or scale B2B cold email, and anyone troubleshooting why emails land in spam. Limitations: it only reads public DNS and registry data and does calculations. It does not send email, change DNS, connect to mailbox or sending accounts, or test actual inbox placement. DKIM keys under custom selectors can't be discovered. Some blocklist operators refuse queries from cloud resolvers, so a list may show as not checked. Results are guidance, not a deliverability guarantee. No account or sign-in is required, and inputs are not stored.

Mailly

Mailly

By DING WANG

Mailly gives Codex and ChatGPT a real two-way email inbox at @mailly.site or your own domain. Search and read threads, including the original HTML, wait for a verification code or magic link to arrive, and draft replies that stay as drafts until you approve them. Sending, publishing and resuming always need your explicit confirmation, and the permissions you grant at sign-in (read, draft, send, manage) are enforced by the Mailly API itself. Teams can also prepare templates, contacts, audiences, campaigns and workflows from the conversation; nothing goes out until you review it. Account administration and billing stay in the Mailly web workspace.

Mailopoly Inbox

Mailopoly Inbox

By Mailopoly

Mailopoly is your unified inbox — one place for everything that reaches you. Today it brings all your email accounts together — Gmail, Outlook, Apple, Yahoo and any IMAP mailbox, including multiple accounts of each — into a single view, filters the noise into a clean personal feed (the Cleanbox), and extracts what matters: tasks, replies owed, invoices with amounts and due dates, deliveries, and events. This connector gives your assistant that same understanding — designed to be the one place you check, whatever the message and wherever it comes from. One connection covers all of it. Ask for "emails about the lease" and Mailopoly searches every account at once (with deep search for harder, semantic queries); ask "catch me up" for a briefing on what you missed; ask "what's on my day" for one list aggregated across every inbox; ask "what bills are due" and the amounts and due dates are already extracted. My Data widgets surface bills, deliveries, replies owed and more at a glance. With write access your assistant manages tasks, reminders, custom email lists and drafts; with send access it sends through your own connected address — never a relay. Permissions are yours: read, write and send are separate grants chosen on a Mailopoly consent screen, enforced server-side on every request, revocable in one click from Settings → Security. Every tool call is audit-logged to your account. Mailopoly is SOC 2 Type II certified and a Google-verified OAuth application. Requires a Mailopoly account — free trial available, no card needed.

Mailora

Mailora

By ArquiTech

Mailora is a privacy-focused European webmail hosted in France. This connector lets your assistant work with your Mailora mailboxes, contacts and calendars: search and read emails and full conversations, organize messages (mark, archive, move, tag), prepare drafts, reply and send with your confirmation, manage contacts, and plan meetings by finding free slots and creating events. You stay in control: on the Mailora consent screen you choose exactly which permissions to grant (read, organize, send, contacts, calendar) and which mailboxes the assistant may access. "Draft-first" mode is on by default, so emails written by the assistant are saved as drafts for you to review and send from Mailora. You can disconnect the assistant at any time in Settings → Developers.

Mailsoftly

Mailsoftly

By Mailsoftly

Mailsoftly is an email marketing and automation platform for growing businesses, nonprofits, schools and PTAs, local governments, associations, professional services firms, marketing agencies, consultants, and corporate teams: organizations where email is essential but not anyone's full-time job. Real people answer support, deliverability setup is something we walk you through, and pricing stays sane as your list grows. Your whole team works in one account. With the Mailsoftly connector, Claude becomes a hands-on assistant for your email marketing. Ask which contact list is biggest, find a subscriber by email, fix a job title, add someone to the webinar list, or have a newsletter drafted and waiting for you to review in Mailsoftly. The same goes for member newsletters, donor appeals, citizen notices, parent updates, client updates, and product announcements. Sending is deliberately a two-step. Drafting and sending are separate permissions, and the permission to send is an opt-in on the consent screen that starts switched off. Leave it off and Claude can still research, draft, and prepare while you press send yourself in Mailsoftly. Every send goes through the same deliverability checks, sender authentication, and suppression rules as a campaign built by hand. Sixteen tools cover contacts, contact lists, tags, custom fields, senders, campaign drafts, campaign status, sending, and unsubscribes. The connector is a remote MCP server run by Mailsoftly on our own first-party API. It reaches only the account you connect it to, only within the permissions you approve, and records which app made which change. Connecting is an admin action, and access can be revoked at any time from Settings > Connected apps. You need a Mailsoftly account and an admin user on it. There is a free plan, so you can try it before you pay for anything. Switching from Mailchimp, Constant Contact, or a similar platform includes free migration of your lists, templates, and signup forms.

Mailsuite

Mailsuite

By Mailsuite

Mailsuite connects your AI assistant to your Mailsuite email tracking, so you can ask about your email the way you would ask a colleague. Know what happened. Ask who opened your proposal, which emails got clicks or replies today, or what your history with a contact looks like. Mailsuite answers from your real tracking data: opens, clicks, replies and recipients. Know who to chase. See the conversations where someone owes you a reply, ranked by how long they have been waiting, and your most active contacts. Act on it. Draft and send a tracked email or a follow-up from your own Gmail address, reply inside an existing thread, or set a reminder that Mailsuite cancels automatically if the contact replies first. You stay in control. The assistant shows you the recipients and the text before anything is sent. Emails to people you have never written to wait for your approval in Mailsuite. Team owners decide whether their team may connect AI apps, and you can disconnect at any time from Mailsuite settings. Requires a paid Mailsuite plan and a Google account with Gmail connected.
